SPECIFICATION forming part of Letters Patent; No. 379,756, dated March 20, 1888.

Application tiled October 22, 1886. Serial No. 216,933. (No model.)

To all whom it may concern:

Be it known that I, J OSEPH O. BANNING, of

Plainville, in the county ofHartford and State of Connecticut, haveinvented certain new and useful Improvements in Fire-Extinguishers, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

My invention relates to the class of devices commonly known as chemical fire extinguishers, and my improvement consists in certain details of the construction of the portable case or receptacle, the fragile vessel located therein, and the means for supporting I5 and crushing it, and in the combination of the several parts, whereby eheapness in construction and efficiency and rapidity of operation are insured, as more particularly hereinafter described, and pointed out in the claims.

Figure l is a top view of a fire-extinguisher made in accordance with my improvements. Fig. 2 is a view in vertical section of the same. Fig. 3 is a detail side view of the top part of the extinguisher, illustrating the operation of z 5 the Valve.

In the accompanying drawings, the letter a denotes the main receptacle, that is a cylindrical vessel of metal of convenient size for carrying readily from place to place, although my improvements also contemplateits use without removing it from a supporting shelf or bracket. On one side of the receptacle is secured a handle, b, and the outlet-tube 0 projectsfrom the top of the same on the side opposite 33 this handle, the lower end of this tube extending within the receptacle and opening near its bottom, so that practically all the liquid contents may be ejected through this tube by the pressure of the gas generated bythe mixing of the chemicals in the extinguisher. The screwcap (1 closes the top of the receptacle, and to it is secured the frame 0, that forms the support for the glass bottle or like fragile vesself, that is adapted to contain part of the chemicals used in the extinguisher. The cap has a central socket, d, in which the sliding spiudleg has a limited vertical play, the spring 9, located between the shoulder at the bottom of the socket and the collar g on the spindle, holding the spindle normally at the'upper limit of its play.

To the lower end of the spindle is secured the crusher h, that is a disk of metal with a rough or irregular under side. This crusher is attached to the spindle by a threaded socket fitting the screwstem on the latter, and is adj ustable to a certain extent, so that it may be located in close contact with the vessel f, that is held in the frame. This frame is secured to the under side of the cover by means of the screw-thread on the hub d and the threaded 6o socket in the upper crossbar, e, of the frame. By means of this construction the distance of the cup 6 from the crusher may be adjusted. The cup-shaped bottom of the frame has a con tral opening to facilitate the outflow o'fliquid from the bottom after it has been crushed, as

by a downward blow upon the top of the spindle, and the two side parts of the frame have metallic arms a, that bend readily to admit a bottle between them or to close upon ahd hold it in place.

On the top of the receptacle is pivoted a lever, 2", that has on its outer end a valve that lies over and closes the mouth of the outletpipe, while the inner end of the lever lies in the path of a projection on the sliding spindle, so that as the latter is pushed inward the lever is tilted and the valve is lifted off the outlettube. The inner end of this, when thus depressed, is caught by the spring-catch j and held until released to close the outlet after the vessel has been again charged.

My improved extinguisher is. charged with the proper chemicals whose union will produce carbonic-acid gas, the fragile vessel containing 8 5 part of the elements being secured in the frame in position to be crushed by the forcible inward movement of the sliding crusher spindle, and is then ready for use. The receiver may be grasped by the handle in one hand and by 0 a violent blow on the spindle the bottle crushed and the outlet opened for the outflow of the charged liquid in astream that may be directed at will upon a flame to be extinguished.

I am aware that it is not new to construct a portable extinguisher of this class with sliding bottle-erushers and a valve in the outlet-pipe automatically opened by the movement of the part that crushes the bottle, and such device I do not broadly claim.

I claim as my improvement- 1. In a chemical fire-extinguisher, the combination, with the receptacle, a cover, and a bottle-crusher sliding therein, of a bottle-supporting frame, 6, having a rigid bottom and open at its sides to permit the inserting of a bottle, and the pliable arms 6, extending laterally to embrace the sides of the bottle to prevent its lateral displacement in the frame, as set forth.

2. In achemical fire-extinguisher, the receptacle having an outlettuhe, a bottle-supporting frame secured Within the receptacle, a sliding crusher-spindle bearing a crusher, and a lever pivoted to the receptacle and bearing on one end a valve adapted to close the mouth of the outlet-tube, and having its other end in the 15 path of movement of a projection on the sliding spindle, all substantially as described.

3. I11 combination with the receptacle having the outlet-tube, the withindeseribed bottle supporting and crushing device, the tilting 2o JOSEPH O. BANNING.
